The course may be divided in three parts: 1- basic principles of design of experiments (1 CFU); 2- quality through experimental design(4 CFU); laboratory: works carried out by the students on real data(1 CFU).

Learning Objectives
The knowledge in order to make quality in a firm, by considering the technological and productive issues. In addition, the customer's feedback may be applied.
Prerequisites
Basic principles of statistics and statistic inference; in particular estimation methods and hypothesis tests.
Teaching Methods
1- Theory; 2- Application of theory through real examples; 3- excercises performed by students with teacher's check.
Further information
The course will be in Florence (Viale Morgagni.
Type of Assessment
oral examination.
Course program
1-Brief introduction to the experimental design: trial, replication, randomization, source of variability, factor role (experimental factor and sub-experimental factor); random and fixed levels; planning.
2-Complete factorial design; interaction; fractional factorial design at two levels: resolution, confounding effects, alias pattern, building of the fractional factorials. Fractional factorial design and robust design, also considering the Taguchi’s philosophy. Response Surface Methodology of I and II order: designs, properties, optimization methods (I and II order), polynomial models.
